The stream - // is implemented on top of IPC, it is connectionless and its - // reliability is as good as what the raw IPC can offer. - // - // Since CLASSIX IPC is not intended to go across wide area network, - // it can be seen as an - // alternative to AF_INET's connection oriented stream, even though - // the CLASSIX IPC is connectionless. - // - // This class contains a local sap, peer sap and data holding - // delivery mode information. - // - // When a stream is created, the peer SAP information must be provided. - // The local SAP information may be provided in the constructor or - // open(). The local SAP information given in open() overrides the - // existing one.
